So I think these two guys are trying to break into my home. I see the same two creepy old guys always driving around my neighborhood in an old van. They always park outside my house and are looking in and spying on me. Some background info, my family is currently in Paris for the holidays so I am left to defend the house myself. Any clever ideas for self defense and home security? I live in a traditionally safe chicago suburb so I am a little surprised this is happening.
